"World's fastest triathlon bike" comes from an unexpected source

For many people, the name "Diamondback" brings BMX and mountain bikes to mind. In fact, though, the company has been expanding into the world of high-end road bikes in recent years. This week at the Ironman World Championships in Kona, Hawaii, that expansion is culminating in the unveiling of the Andean – reportedly the world's fastest triathlon bike. It will be ridden by Olympian and multiple-time Ironman winner Michael Weiss.

The Andean has been in development for the past two years. It was created in partnership with Kevin Quan Studios utilizing wind tunnel testing facilities at the University of Toronto Institute for Aerospace Studies, where it is claimed to have outperformed all other "competitive models."

As can be seen, its carbon fiber frame is quite … big. Known as an "Aero Core," this airfoil design is intended to minimize drag, as air passes relatively unimpeded from the front wheel, along either side, and off the back wheel. The idea is to fill up the empty space between the two wheels, minimizing turbulence.

There are also plenty of places to store things. Integrated compartments on top can carry three water bottles, three energy bars and 10 gel packets, while a lidded cubby hole located in front of the cranks holds roadside tools and a spare tube. Oh yes, and there's also a place behind the seat post, where the rider can stash their wallet.

Should you be interested in getting one, the Andean is available now for pre-order in five builds.

The base model, which features a SRAM Force X1 drivetrain and HED Ardennes Plus wheels, is priced at US$4,779.99. At the other end of the scale, a version equipped with a Shimano Dura-Ace Di2 drivetrain, Dura-Ace hydraulic disc brakes and HED Jet Black 9 wheels will set you back $8,069.99. Weight will vary with the component mix, although one of the mid-range builds is said to tip the scales at 20.5 lb (9.3 kg).

Sales will be by direct order only (so don't go looking for one in the stores), with deliveries expected to begin at the end of next January.
